不聚焦

Does your artwork especially focus on virtual reality?

6：你的作品是不是特别聚焦在「虚拟世界」的概念上？

This paper focuses more on the experience of VR than the technology.

本论文主要聚焦於VR的体验，而不是VR的技术。

In dual-frequency laser interference measuring system Wollaston prism is an indispensable and important device,which can separate the incident beam in to measurement beam and reference beam according to the polarization direction of dual-frequency laser,so as to realize the high accuracy measurement.

在双频激光干涉测量系统中，Wollaston棱镜是不可缺少的重要光学元件，它可将双频激光按偏振方向分为测量光和参考光，从而实现高精度测量；但是，如果Wollaston棱镜的安装方位相对入射光线方向以及与聚焦透镜距离不同时，测量结果将会不同。

Focal error signal of pickup head is achieved according to the Astigmatical principle, and that the optical non-contact probe system with the measurement ranges of 2um and the measurement uncertainty of 1.1nm is obtained. This probe system is immune to the variation of reflective ratios and curvature on the surfaces of samples via improvement of the signal process method.

其中根据光学象散原理得到激光读取头的聚焦误差信号，从而获得测量范围为2μm，测量不确定度可达1.1nm的光学非接触探头系统，通过改进信号处理方式，此探头系统可不受材料表面反射率变化的影响，并允许样品表面存在一定的曲率变化。

Because of hole on foils, only small part of electron beam bitted on the foils, the device can be operated repeatedly.

这些器件不需要外加磁场聚焦电子束，波束相互作用区短，功率容量大，结构简单，输出信号稳定，可以实现器件的小型化；电子束调制和微波能量提取分开进行，可以提高器件的效率而且便于参数调节。

The computation analysis indicates that increasing the aperture of the concave focusing transducer, decreasing it's geometric focal length or raising it's central working frequency can improve the transverse and axial resolutions of the system simultaneously, but changing the dividing proportion of the transducer affects the two kinds of resolution differently. On compromisingly considering several factors including the exciting mode, the focusing ability and the radiation force effect, the concave focusing transducer should be divided into two equal-area parts.

计算研究表明：增大凹球面换能器的口径、减小几何焦距和提高中心频率均可以提高系统的侧向分辨率和轴向分辨率；但改变凹球面换能器的分割比例对两种分辨率影响不尽相同综合考虑超声换能器激励、聚焦性能以及产生的辐射力效果等因素，则换能器应按等辐射面积原则分割为宜。

Security Indolence Non-invasive and non-ablative RF with particular epidermis cooling system, which can make the epidermis to 1-5℃. No need hocus, no need convalescence, no influence for client's life.

优势聚焦 Advantage ◆安全无痛-非侵入、非手术性拉皮术，独有的表皮冷却系统，可预先将表皮冷却到1-5℃，无需麻醉，无需恢复期，不影响治疗者的正常生活作息。

Such a telescope does not need any thermal control as its behaviour under homogeneous temperature changes is perfectly homothetic and thus keeps the image focused onto the detector.

这样的一个望远镜结构不需要任何的温度控制，因为在均匀的温度变化下热形变也是一致的，可以保证图像在探测器件上维持聚焦。

With an unfocused visual treatment, artist put actress on semi-transparent, illusional surface just like fading ancient mural paintings; the emotion is intensive, sentimental and fragile.

传统图式中戏子的脂粉红颜和秋波明眸在永恒弥坚的山水之间朦胧动人，紧张、绚丽、刻意的聚焦不清晰、图像化倾向与作品中戏剧化情感的极度张力相结合，贴切、恰当地隐寓古典精神如镜花水月般的憔悴凋零，是经典沦落的伤情挽歌。

In this study, isoelectric focusing electrophoresis program was optimized, and various sample preparation methods, different loading quantities and strip length were studied.

在实验中，优化了等电聚焦程序，研究了精子蛋白的不同制备方法、不同上样量、不同胶条长度对电泳结果的影响。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
